Hi all,I'm looking of purchasing sram etap for my race bike. I'll be on a standard 53-39 chainset and am debating whether to go wifli or not. I don't really see myself racing with anything bigger than a 28, I only used bigger in one race till now. However if the wifli rear mech runs well with an 11-25 and 11-28 I'd prefer to go this way as I like the idea of throwing in a 30 or 32 for foreign holidays. Anyone with any experience? I'd really appreciate some input. Thanks,Cathal.

I've used a wifli mechanical RD with an 11-25 and it did not shift as well as with a regular mechanical RD. Slightly less crisp. I'm not sure if eTap would be better in this regard. I'm currently on regular eTap but have not tried the wifli version.

Any more feedback on this? Currently considering the same choice myself. Would be running 53/39 and 11/28.

What with Shimano running a longer cage these days is Wifli the better option? Also, do longer cages save on watts? I remember Cancellara running a long cage for drive train friction purposes before long cages were even the norm on road bikes.

I fit the Etap Wifli onto my light bike for the rare occasions when I travel out and get to do some real climbing, but for my upcoming bike I'm pretty sure I wouldn't be travelling with it so a normal short cage will do just fine and I get to save a 100 bucks on it. Not sure why most don't use a Wifli but if you know your terrain you can just get whatever fits.

I managed to fit a pair of 12t-14t pulley wheels into the Wifli think that'll save a bit of watts.
